Russian press quotes Sergey Boyev, the chief designer of the early-warning system, as saying that Russia may consider building a new early-warning radar in Crimea, most likely at the site where the Soviet Union deployed a Dnepr radar. The new radar was referred to as Voronezh-SM, where SM stands for "centimeter-range." A shorter-wavelength radar can provide a better tracking accuracy, albeit at shorter ranges.

According to Boyev, the radar that is being built in Vorkuta is also a centimeter-range Voronezh-SM. (This confirms the earlier find, which suggests that there are two radars under construction there.)
